摘要： 705,399. Hay-sweeps. THOMPSON, W. T., ALDERSON, T., and THOMPSON, J. F. April 15, 1952 [April 12, 1951], No. 8530/51. Class 6 (3). [Also in Group XXX] A tractor-pushed hay-sweep has metal tines I each with an upstanding longitudinal reinforcing rib 3 which engages a slot 6 in each of two transverse frame bars 4, 5, separate plates 7 being provided for removably securing the tines in place. At the outer end, the rib is tapered off and the tine is shaped and curved upwardly. The end portions 9 of the frame bars may be hinged at 10 to swing upwardly to lessen width for travelling or to provide a sweep of scoop form. The sweep is mounted on the tractor by a hinge bar 13 allowing free rise and fall during working or to permit raising by winding gear or the power lift on the tractor.

摘要： 359,209. Illusion apparatus. THOMPSON, W. T., 107, Irving Street, Birmingham. Oct. 22, 1930, No. 31679. [Class 132 (iii).] A coin-freed mystic mirror machine comprises a metallic globe 7, Fig. 1, of lustrous appearance having a view tube 8 provided with a mirror 9 which normally reflects an observer's image but becomes transparent on illumination by a lamp 11, screened by a translucent plate 10, so as to display transparent exhibits 6 mounted in plates 5 on a rotatable carrier 4. On inserting a coin the carrier 4 is rotated so as to bring one of the exhibits 6 behind the mirror 9, this being simultaneously illuminated by the lamp 11. Delivery of articles stored in piles.-Tickets 22, Fig. 4, are ejected by a slide 24 operated by a lever 26 which is pivoted at 26a, 27a to a frame 26b and lever 27 respectively. The lever 27 is rocked by a pin 30 of a cam 29 on a shaft 12, rotated after the insertion of a coin engaging a slot 28, the pin being held at the end of the slot by a spring 31. If the slide 24 is jammed and the lever 26 held stationary, the pin 30 moves along the slot 28 allowing the lever 27 to rotate about its pivot 27a and preventing jamming of the shaft 12.
